ARCHIVE POLICY
ASCE is committed to the long-term preservation of its digital journal content and has arranged for secure archiving with Portico and CLOCKSS to ensure that ASCE journals are preserved and available for future scholars, researchers, and students. The archival record will include the back issues of all ASCE Journals, E-books, and Proceedings currently available at ascelibrary.org .

CLOCKSS LOGO CLOCKSS (Controlled Lots of Copies Keep Stuff Safe) is a community-governed, non-profit joint venture between the world's leading scholarly publishers and research libraries to secure the permanent availability of digital content.

 PORTICO LOGO Portico is a digital preservation service provided by ITHAKA, a not-for-profit organization with a mission to help the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways.

USAGE RIGHTS OF ACTIVE INSTITUTIONAL SUBSCRIBERS
Usage rights of active institutional subscribers will be governed by the terms of the then current Subscriber Agreement, a signed copy of which must be on file. A subscription fee for the current term must also have been paid. Distribution to parties beyond that defined in the Subscriber Agreement may be permitted upon explicit agreement with ASCE. Additional rights may be provided to institutions purchasing extended access methods.

POST-CANCELLATION POLICY
Institutions may request post-cancellation electronic files on DVD for a nominal fee for the period during which an online subscription was held.

The same usage rights as for active subscribers apply to use of the physical archive copy. Upon lapse of subscription, no additional service is provided. Lost or damaged physical archive copies will be replaced with copies in the then-current format for a reasonable fee; otherwise, back issue physical copies in the then-current format will be made available at the current pricing schedule.

It is important to note that although ASCE will make available a physical archive copy of information covering a specific subscription term, the physical archive copy may not contain all linking and other features inherent in the online version of the journal available to active subscribers. ASCE does not guarantee that links and other features intended to function within an active subscription will continue to be available in the years following delivery of the physical archive copy.

USAGE RIGHTS OF NONSUBSCRIBERS
Pay-per-article access will be provided. Physical copies of current or back issues will be made available at the then current pricing schedule.

ASCE COMMITMENT TO RETENTION AND PRESERVATION
The American Society of Civil Engineers will retain in an archive all electronic information published by ASCE through our partnership with Atypon's LiteratumTM platform. Original source material will not be altered, except in extraordinary cases of production errors or similar situations, in which case there will be a clear record of the change. Source material may be annotated or supplemented by clearly noted errata, references, and other developments that may occur subsequent to original publication.

In cooperation with Atypon, ASCE will hold a primary source material archive and be responsible for the periodic refresh of this archive (to assure its continuing availability) and its replication to additional archives. The primary source material archive will not be used for active delivery. At least one complete archive will be maintained at a site separate and distant from the primary archive.

The archive will be reviewed for refreshing or migration to new information formats at appropriate intervals. The initial archive material will be in the predominant current standard (e.g., XML-based) with suitable current standard-based storage formats for figures, page images, and other information forms as they develop. Information will be migrated to new formats when current formats are in danger of becoming obsolete or unsupportable, or when new formats provide substantial improvements in features with no loss of content.
